ESD PE-Schaum

ESD-PE-Schaum ist eine Art antistatischer, geschlossenzelliger Polyethylenschaum in schwarzer Farbe. Es handelt sich um einen umweltfreundlichen, elektrostatisch schützenden Industrieschaum mit geringer Dichte für die Verpackungsindustrie. Als Schaum Oberfläche Widerstand Unterschied, hat es antistatische PE-Schaum und leitfähigem PE-Schaum zwei Arten. Antistatischer PE-Schaum hat einen Oberflächen- oder Volumenwiderstand von 10^6-109 Ω, und leitfähiger PE-Schaum hat einen Oberflächenwiderstand oder Volumenwiderstand von 103-105Ω.
